' `IMPROVEMENT IN FANNING-MILLS.

Specification forming part of Letters Patent N0. 35,463, dated June 3, 1862.

`To all whom it may concern:

Be it known that I, JACOB MILLER, of Canton, in the county of Stark and State of Ohio,

have invented certain new and useful Improvements in the Construction of the Shoe and lRiddles of Fanning-Mills; and I do herebyr declare the following to be a full, clear, and exact description of the construction and operation o f the same, reference being had to the accompanying drawings, making a partof this speciiication, in which Figure 1 represents a longitudinal vertical section through the shoe and its several parts. Fig. 2 represents a vertical transverse section at the line ai x of Fig. l.

Similar letters, where they occur in the .drawings,denote like parts of the shoe in both iigures.

My invention consists in the arrangement of an Lipper and lower riddle in the shoe with a chute board between them and the second blast-passage and delivering-spout, so that the grain as it passes through the upper riddle will be carried back and fall on the lower riddle to receive a second action of the air from the same blast as it passes to the deliveryspout.`

To enable those skilled in the art to make and use my invention, I will proceed to describe the same with reference to the drawings. Arepresents a shoe for afanni'ng-milhwhich may be suspended to the frame or sides ofthe purities as pass through the riddle, and are too` heavy to be carried out by the blast under the riddle,drop upon the conducting-board D,and are directed onto a second riddle, E, at the point b, and as the grain and its accompanying impurities pass over this riddle E they are subjected to a second current of air through the passage F,which current may come from the same fan-blower that furnishes the blast to the upper riddle, c. The air-passage F is furnished with a hinged wind board, G, by which the force of the current can be regulated. 'The cleaned grain,dropping upon the directingboard H underneath the lower riddle, is carried into the trough I,and,dropping upon an inclined board, J, in said trough, may be carried out to the side of the machine. The board J may be pivoted at c, so that the grain may be carried to either side of the machine that may be desired or most convenient forits reception. p j

The chaff, dust, and light impurities blown out of the grain as they drop through the first riddle pass out at d, and thence into the trough Aa; or the end boards,e f, both of which may beraised, removed, or adj usted, may be so set as to allow these impurities to pass off at the end of the machine. The impurities driven off by the second riddle and current of air may pass off at g, as well as those which go to the end of said riddle, said riddle extending to the farther side of the trough or slightly beyond it.

This machine may be built and used in connection with thrashing machines, so as to thrash and clean the grain in one continuous operation, or for cleaning and separating thrashed grain, it being applicable to both operations,whether joint or separate.

Having thus fully described the construction and operation of my shoe for tanning-mills, what I claim therein as new, and desire to secure by Letters Patent, is-

The arrangement ofthe riddles C E and conducting-board D with the two wind-passages and the delivery spout or trough I, for the purpose of subjecting the grain to a double or second current of air to clean it, .substantiallyr as described.

JACOB MILLER.
